Helen Mirren, 79, uses this serum before every red carpet and it's 50% off

Not only A-listers but dermatologists swear by this serum, calling it the "ultimate multitasker in skincare."

Dame Helen Mirren is definitely one of our personal icons. A superstar for over six decades, she's one of the most celebrated actresses in history — read: one Oscar, four Emmys and four BAFTAs — but on top of that, the 79-year-old combines her onscreen virtuosity with a cheeky, irreverent wit and timeless beauty. We're also obsessed with the skin-care tips she's given over the years. Whether for promoting the healthiness of hair, skin and nails or a cream that promises to bestow a lovely rosy glow, La Mirren is always up for turning us on to ace, affordable beauty products. The latest entry in that pantheon? L’Oréal Paris Revitalift 1.5% Pure Hyaluronic Acid Serum, her trusted pre-red carpet must-have and a product that, according to the brand, is the number-one selling serum in America. Best of all, this skin-loving salve is down to $18, from $36 — that's 50% off.

This superstar-favorite serum has been shown to replenish moisture for plumped, youthfully supple skin in as little as one week, says L’Oréal Paris.

A-lister-approved skincare at a drugstore price? We love it! Along with Dame Helen, thousands of five-star reviews from customers confirm that not only is this serum a great product. "This stuff did wonders for my skin," one reviewer said. "Absolutely always keep coming back to buy again. And it's cheaper than the store." Right now its Amazon price is nearly as low as it goes — grab a bottle for yourself for just $18, down from $36 — a 50% markdown.

So how does Dame Helen use this little wonder? In a recent Cannes tell-all with The Telegraph, she revealed that while "I don't really have any [pre-red carpet] rituals per se," she does do one thing before her makeup artists get to work: She preps and moisturizes her skin using L’Oréal Paris Revitalift.

This top-rated bestseller is backed by dermatologists too. “[It] was clinically tested for both stability and effectiveness,” NYC dermatologist Joshua Zeichner tells Yahoo Lifestyle. He served on the external advisory panel of docs who had access to the development and research of the serum and validated L’Oréal’s claims.

What makes this serum such a skin-care standout? Its main ingredient. “Hyaluronic acid is a humectant ingredient that pulls in hydration to the skin to plump and moisturize,” explains Zeichner. “It acts like a sponge and can bind to 1,000 times its weight in water.” Zeichner calls the hydrating active ingredient the “ultimate multitasker in skincare,” adding that improved hydration results in the minimized appearance of fine lines and a boost of radiance. All it takes is a few drops in the morning and night, he says.

The best part is that the serum is suitable for all skin types. “It can be used across all skin types, even in those with sensitive skin,” he says, adding that those with dry or dull skin will reap those hydrating benefits as well.

What reviewers say 💬

This luxe liquid isn't just for big names — Amazon shoppers are big fans too, with 34,000 five-star reviewers raving about the formula.

“I feel I look five years younger,” one chimed in. “My complexion is incredible. Can't imagine going without this product ever again.”

"Simply amazing," raved another. "After using the serum consistently for a few weeks, I've seen a noticeable reduction in fine lines and an overall improvement in skin elasticity. My complexion looks brighter and more youthful, and the added hydration has helped to reduce dry patches and flakiness."

“It didn’t take long to tell this stuff works! I noticed changes in my skin texture after one use, and now it’s been about 10 days, and my skin is so smooth, soft, and even-toned,” another reviewer dished. “Can’t believe it. I don’t even feel the need to wear foundation.”

Some shoppers felt their skin didn't agree with the ingredients. "If you're sensitive to [retinol], I'd recommend you move on to something else," a shopper advised.

According to this customer, "I’ve used other hyaluronic acids that I thought were more moisturizing than this. There’s something about the texture of this that’s kind of odd."

An amazing 34,000 shoppers are fans of this popular anti-aging serum!
